What is an appropriate typeface style for highlighted text?

Using standard serif fonts for highlighted text is appropriate because these typefaces are generally easy to read and help convey information clearly. Serif fonts feature small lines or embellishments at the ends of their characters, which can improve readability, especially in print. This legibility is crucial when highlighting key points or information to ensure that the audience can quickly grasp the essential content without becoming distracted or confused.

In contrast, all caps lettering can be perceived as shouting, which may come across as aggressive rather than helpful. Dramatic typefaces often sacrifice clarity for style, making it harder for readers to process the highlighted content quickly. Long lines of italic type can also hinder readability; while italics can be useful in specific contexts, they can become cumbersome when overused or when presented in long stretches, making it difficult for readers to maintain focus. Overall, standard serif fonts strike a balance between highlighting important information and maintaining readability, making them the most suitable choice for emphasized text.
